paxta fuel mapper question..

i have a 94 lt1 camaro with a novi gss @ 7.5#. i bought the car with this and an msd ignition setup. it has the 6btm box which i have had to replace twice. has anyone had a similar setup to this? my main concern is this programable fuel map curve box. i have been trying to trace the circuit to which its connected to and is leading me to believe its hooked up the the ignition system. however im a newbie at these setups so im still learning. also this particular box has 10 leds on it and an off/ output button. im quite confused and there is limited info on the net about this particular programable fuel map curve box. someone please help and explain this box to me like im a 5 year old!! lol thanks alot
